Vintage F250 RV's

Post #1 by MechRick » Tue May 06, 2014 9:58 pm

I dug up something on C/L yesterday that I thought was very interesting. Apparently Dolphin and Shasta made class C RV's on early 80's Bullnose F250 chassis. 4.9L power with C6 automatic.

The one I'm looking at is 20' long. I've been trying to dig up GVW numbers to figure out the weight to get a guesstimate on performance and towing weights. Chassis weight I'm guessing at 5000 lbs, with the box weight probably coming in at ~3000 lbs to satisfy the 7,700 GVWR. My half ton with 10,000 total weight still performs reasonably well (hey, it's not a Powerstroke), so I'm thinking an RV with the big six should be doable. Certainly better than a 22R-powered Toyota Dolphin anyway.

My White Ox weighs 7000 lbs empty and the car hauling trailer is 3000 lbs, so when I go to haul hay it is right at 5 tons before I lift a bale. Add 5 ton of hay and it does get a bit sluggish.

So long as you don't get in a hurry you will be fine. I like it :thumbup: :nod:

I had for a very short period of time a 1980 F250 HD it was 8600GVW.

I remember seeing a mid 1985? 80s F250 at 6600 GVW it had 8 lug wheels and a 8.8 rear axle. (looked odd to me.)

Mercy sakes! :shock: That thing was overloaded when it was empty (assuming license for 8000 lbs GVW, a typical rating in Idaho).

The Clark Cortez got from there to here with a slant six, except when the right front wheel unscrewed itself thanks to some neanderthal engineering. Maybe lift trucks reverse direction so often that reverse threads aren't needed. Thankfully that saga, and that boyfriend, has departed from my daughter's life. The Cortez is parked somewhere.
Back on topic: our sixes liked being loaded. There are thousands of plumbers and electricians out there in chronically laden E250s. The EFI versions are more suitable unless you up the ante with cam and carburetor mods.
What's a bullnose F250?

That's the internetically- approved nickname for '80-'86 F-series trucks due to the reverse line of the front grill (like '80's BMW's).

Reg Cab, long bed with a 300 4-Sp trans Dana 60 rear axle and NO options other than PS/PB. It was formerly owned by a construction company and looked the part. I'd think the truck weighed no more than 5100Lbs.

80 models F150s, and F250 had holes in the frame to lighten them up. up to about 82? I think.
My full size Bronco has the holes as well.
